Source-derived summary

Seabiscuit (May 23, 1933 – May 17, 1947) was a champion thoroughbred racehorse in the United States who became the top money-winning racehorse up to the 1940s. He beat the 1937 Triple Crown winner, War Admiral, by four lengths in a two-horse special at Pimlico and was voted American Horse of the Year for 1938.

A small horse, at 15.2 hands high, Seabiscuit had an inauspicious start to his racing career, winning only a quarter of his first 40 races, but became an unlikely champion and a symbol of hope to many Americans during the Great Depression.

Seabiscuit has been the subject of numerous books and films, including Seabiscuit: the Lost Documentary (1939); the Shirley Temple film The Story of Seabiscuit (1949); a book, Seabiscuit: An American Legend (1999) by Laura Hillenbrand; and a film adaptation of Hillenbrand's book, Seabiscuit (2003), that was nominated for the Academy Award for Best Picture. There is also a street in Indian Trail, North Carolina named after him.

Background and early days

Seabiscuit was foaled on May 23, 1933 at Claiborne Farm in Paris, Kentucky. He was a result of owner Gladys Phipps' breeding of the infamous Hard Tack and one of her mares Swing On. Seabiscuit was named for his father; "sea biscuit" is another name for hardtack, a type of cracker eaten by sailors.

The bay colt grew up at Claiborne Farm where he was trained. He was undersized, knobby-kneed, and given to sleeping and eating for long periods.

Editorial analysis

Why this record matters

The phrase “champion thoroughbred racehorse in the United States” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
